Humidification control system and method for ventilation therapy equipment

Abstract

The application provides a humidification control system and method for a ventilation therapy device, including a ventilation therapy device main body, a respiratory humidifier, a heating circuit, and a nasal oxygen tube, wherein: the ventilation therapy device main body includes a fan and a first controller; The humidifier includes a water tank, a heating plate, a temperature sensor at the inlet of the water tank, and a temperature sensor on the heating plate; among them, the air outlet of the fan is connected to the air inlet of the water tank; the air outlet of the water tank is connected to the air inlet of the heating pipeline The air outlet of the heating pipeline is connected with the input port of the nasal oxygen tube; the heating pipeline includes a temperature sensor at the inlet of the heating pipeline and a heating control module of the heating pipeline; the first controller makes the water vapor in the current water tank The relative humidity of the first mixed airflow obtained after mixing with the air input by the fan is the target humidity. The present application ensures that the airflow inhaled by the patient is a mixed airflow conforming to the target temperature and humidity, so as to ensure the comfort of the patient.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a humidification control system and method for ventilation therapy equipment. Background technique [0002] High-flow heated humidifier is a new type of respiratory therapy equipment that can humidify high-flow gas mixed with oxygen and deliver it to patients. The device can be set according to the specific needs of the patient, output the corresponding flow of air, or mix the oxygen from the outside with the air in the environment, heat and humidify it to a suitable temperature and humidity, and deliver it to the nasal cavity of the patient. [0003] However, within a period of time when the humidifier is first started, because the water used for humidification has not absorbed enough heat, it cannot evaporate enough water vapor immediately. In order to ensure the humidity of the air inhaled by the patient, when the humidifier starts to operate, it needs ...

Problems solved by technology

However, in actual use, especially at home, the patient may use the humidifier under reasonable environmental conditions, which may cause the patient to wear the nasal oxygen tube before the preheating is completed, resulting in the humidity of the air inhaled by the patient And the temperature is not suitable, not only will not play a therapeutic effect, but may also cause damage to the patient's respiratory tract
